ABST RACT Dichelobacter nodosus from ovine footrot was characterized for pgr and intA genes. Out of 260 samples collected from clinical cases of ovine footrot only 107 were found positive for D. nodosus by species-specific 16S r RNA-PCR. The overall prevalence of footrot based on clinical symptoms was estimated to be 10.57%. Serological diversity studies based on fimA gene revealed the presence...

BACKGROUND Published data on the epidemiology of meningococcal disease in Latin America and the Caribbean region is scarce and, when available, it is often published in Spanish and/or in non-peer-reviewed journals, making it difficult for the international scientific community to have access. METHODS Laboratory data on 4,735 Neisseria meningitidis strains was collected and reported by the Nat...

We report on 13 patients diagnosed with meningococcal infections in patients attending state-owned hospitals serving an indigent population in Pretoria in 2009. The case fatality rate was 27%. Ceftriaxone was the main antibiotic (9 out of 13 patients) for therapy. Five isolates (39%) were serogroup B and 4 (31%) serogroup W135. Most isolates (12/13) were fully susceptible to penicillin (MIC ran...

Neisseria meningitidis retains its ability to cause endemic and hiperendemic disease in human population living in any environment, as well as localized outbreaks and massive epidemics in civilians and military personnel. In Rio de Janeiro it has been reported in the 1990s as prolonged outbreak of serogroup B and at least one epidemic of serogroup C was well defined, both demanding quick action...

BACKGROUND Invasive meningococcal disease (IMD) is a major cause of bacterial meningitides and septicaemia. This study shows the results of the laboratory-based surveillance of IMD in Belgium over the period 1997-2012. METHODS The results are based on microbiological and molecular laboratory surveillance of 2997 clinical isolates of N. meningitides received by the Belgian Meningococcal Refere...

BACKGROUND In Niger, epidemic meningococcal meningitis is primarily caused by Neisseria meningitidis (Nm) serogroup A. However, since 2002, Nm serogroup W135 has been considered to be a major threat that has not yet been realized, and an unprecedented incidence of Nm serogroup X (NmX) meningitis was observed in 2006. METHODS Meningitis surveillance in Niger is performed on the basis of report...

Background: Despite of the amount of work on the meningococcal serogroup B bacteria and immunity to disease caused by them, a satisfactory vaccine for these important pathogens is still missing. Several group B meningococcal vaccines based on outer membrane protein vesicles (OMV) or complexes have been evaluated in phase II and III clinical trials. Although the antibody responses in connection ...

Neisseria meningitidis, a leading cause of bacterial meningitis and other serious infections, is responsible for approximately one-third of cases of bacterial meningitis in the Children's Hospital of Tunis. The serogroup distribution, antibiotic susceptibility and antigenic and molecular characteristics of N. meningitidis isolates were determined in patients aged 3 days-13 years between Februar...

Pili of Bacteroides nodosus 265 (serogroup H) were expressed in Pseudomonas aeruginosa both alone and in combination with pili from B. nodosus 198 (serogroup A). Pilin genes from B. nodosus were introduced on plasmid-borne, thermoregulated expression systems, either singly or as tandem genes from two separate strains in a single transcription unit. Despite the absence of a posttranslational cle...

In the report "Advisory Committee on Immunization Practices Recommended Immunization Schedule for Adults Aged 19 Years or Older - United States, 2017," on page 138, the fifth bullet point under the heading "Meningococcal vaccination" should have read "Young adults aged 16 through 23 years (preferred age range is 16 through 18 years) who are healthy and not at increased risk for serogroup B meni...
